3A and 3B CSA Review

Front

What is the name of the molecule that unzips the DNA Helix?

Back

DNA Helicase is the enzyme that unwinds the DNA double helix during DNA replication.

Front

What are the three parts found in all nucleotides?

Back

All nucleotides consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the role of DNA Polymerase in DNA replication?

Back

DNA Polymerase is the enzyme that adds complementary nucleotides to the growing DNA strand during replication.

Front

What is the process of translation in protein synthesis?

Back

Translation is the process where mRNA is decoded to build a chain of amino acids, forming a protein.

Front

Where does translation occur in the cell?

Back

Translation occurs in the ribosome, where mRNA is translated into a protein.

Front

What is the function of RNA Polymerase?

Back

RNA Polymerase synthesizes RNA from a DNA template during transcription.

Front

What are the differences between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that codes for a specific amino acid.

Front

What is the significance of the start codon?

Back

The start codon (AUG) signals the beginning of translation and codes for the amino acid methionine.

Front

What is the role of tRNA in translation?

Back

tRNA (transfer RNA) brings the appropriate amino acids to the ribosome during protein synthesis.
